The Late Natufian at Raqefet Cave: The 2006 Excavation Season

International audienceA long season of excavation took place at Raqefet cave during the summer of 2006. In the first chamber we exposed an area rich with Natufian human burials (Locus 1), a large bedrock basin with a burial and two boulder mortars (Locus 2), an in situ Natufian layer (Locus 3), and two areas with rich cemented sediments (tufa) covering the cave floor (Loci 4, 5). The latter indicate that at the time of occupation the Natufian layers covered the entire floor of the first chamber. During the ensuing millennia, these were washed away and/or removed by later visitors to the cave. We found in the cave and the terrace almost 80 human-made bedrock holes (most of which are commonly but somewhat erroneously termed mortars and cupmarks). Several contained in situ Natufian remains, and at the top of one a human skeleton was unearthed. The variety of the HBHs, in terms of shape and dimensions indicates that they were used in many ways, some of which could not have been for food or mineral processing. The paper provides results of on-going studies regarding the burials, the HBHs,the flint assemblage, the faunal remains, the ground stone industry, the bone tools and the beads. It also presents aspects of geoarchaeology and ground penetrating radar analyses. Some of the detailed plans and sections were prepared by the use of photogrammetry

A Late Bronze Age II Clay Coffin from Tel Shaddud in the Central Jezreel Valley, Israel: Context and Historical Implications

To the memory of Trude Dothan 1922–2016. During trial excavations carried out in 2013 on behalf of the Israel Antiquities Authority, a seemingly isolated clay coffin with anthropoid lid, containing a single primary burial, was uncovered within a 6 m × 5 m probe bordering the lower east slope of Tel Shaddud in the Jezreel Valley. It lay at the bottom of a tightly constricted burial pit, about 1.8 m below the present surface. Subsequent salvage excavations in 2014 uncovered, less than 3 m to its south-east, a further three burial pits (none of which contained a coffin), enclosing four additional primary burials, oriented east to west — in conformity with the coffin burial. Together these burials form part of an apparent Late Bronze Age II–Iron Age I burial ground at the eastern margin of Tel Shaddud. The coffin and associated funerary gifts bear a strong resemblance to comparable specimens and associated funerary assemblages known foremost from Deir el-Balah in the Gaza strip and Bet Sheʽan in the Jordan Valley. The shared mortuary aspects of Tel Shaddud and the latter sites indicate a strong link with New Kingdom Egypt. Based on the Tel Shaddud data and its very location, in combination with selective reading of relevant, near-contemporary historic records (i.e. the el-Amarna letters) it is argued here that Tel Shaddud was a way station, or estate, functioning within the framework of the Egyptian New Kingdom colonization of the region during the Late Bronze Age II and succeeding Iron Age I

Genetic testing and common disorders in a public health framework: how to assess relevance and possibilities

This paper discusses genetic testing and common disorders from a health-care perspective. New possibilities for genetic testing confront health-care workers with the question of whom to test and which test to use. This document focuses on genetic testing and screening in common disorders. The term ¿common disorder¿ is used for disorders that individually have a high impact on public health.Examples of common disorders include cardiovascular disease (CVD), stroke, diabetes, cancer, dementia, and depression. For a health-care practitioner ¿ unlike a geneticist or an epidemiologist ¿ it may not be clear whether a common disorder is due to one gene with a high risk of serious disease, or due to a combination of several genes and several environmental factors. This document will not consider germline prenatal or preconceptional testing, nor testing of biomarkers for tumor recurrence, but it will discuss testing of mutations in tumor tissue, since this may reveal susceptibility to certain forms of therapy. Also, pharmacogenomic applications will not be discussed in depth, although some examples will be given of pharmacogenomic testing. The outlne is as following: First, the terrain of common complex disorders is introduced. Different assessment frames for genetic testing and screening are discussed. The section following that examines the aims and strategies for genetic testing and screening in common disorders and discusses some examples of current testing and screening in Europe. The section ¿The economic evaluation of genetic tests¿ discusses the cost¿benefit relation of different types of tests and screening strategies and how they could be used in the clinic in a cost-effective way. The subsequent section addresses the ethical, legal, and social issues of testing and screening in common disorders. The last section addresses regulatory and intellectual property issues in the EU as well as the United States.JRC.DDG.J.2-The economics of climate change, energy and transpor

GNU Radio

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available, low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems
